Brian Will follows up his earlier anti-OOP video by walking through four short code examples, including Java code in the style of Uncle Bob, to show how object-oriented design complicates simple programs. It argues that OOP hides and scatters state and adds needless indirection.

Stuart Halloway's satirical talk describes how to protect yourself from industry change by spreading complexity through systems while following idiomatic practice. It uses this inversion to catalog software design anti-patterns.

Alex Martelli's Google Developers Day talk on classic design patterns (creational, structural and behavioral) and how they appear in Python. He stresses that patterns must be studied in the context of the implementing language.

Robert C. Martin (Uncle Bob) talks about clean architecture and design, including keeping the database and frameworks out of the center of an application. It is an hour-long conference talk.

Erik Meijer argues that category theory is the mathematicians' version of interface-based design. He shows that Java 8 lambdas and method references form a Cartesian closed category.

John Ousterhout, Stanford professor and creator of Tcl, presents the ideas of his book A Philosophy of Software Design in a Talks at Google session. He covers managing complexity, deep modules and interfaces, and what he teaches in his Stanford software design course.

Rich Hickey's talk at Clojure's tenth anniversary on the kind of programs Clojure is designed for. He argues for situated programs that deal with changing requirements, and for dynamic typing and data over static types.

Casey Muratori shows how typical 'clean code' object-oriented patterns can cost large factors in performance. He benchmarks them against simpler data-oriented code.

Brian Will critiques object-oriented programming and rewrites a roughly 3800-line OO program in a procedural style, cutting code and complexity. It is part of a series of OOP critiques.
